2. A 02-series ball bearing is to be selected to carry a radial load of 8 kN and a thrust load of 4 kN. The desired life LD is to be 5000 hours with an inner-ring rotation of 900 rpm. What is the basic load rating that should be used in selecting a bearing for a reliability goal of 0.90? 3. The bearing of problem 2 above is to be sized to have a reliability of 0.96. What basic load rating should be used to select a bearing with this increased reliability?
